[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 5 , this embodiment provides a technical solution: a plastic crusher tool holder, including a support frame 1 and a bin 12 installed on the support frame 1. A crushing bin 5 is arranged on the upper side of the bin 12. A rotating shaft 9 is installed in the crushing bin 5 and the bin 12. A tool holder fixing plate 10 is circumferentially arranged on the rotating shaft 9. A crushing knife 8 is installed on the tool holder fixing plate 10. A loosening prevention plate 11 is vertically arranged on the tool holder fixing plate 10. Support arms 6 are symmetrically arranged on one side surface of the bin 12. An electric push rod 7 is arranged on the side of the crushing bin 5 away from the support arm 6.

[0021] As Figures 1 - 5As shown in the figure, when plastic is being crushed, the plastic is fed through the feed bin 4, and the waste plastic enters the crushing bin 5. The motor 2 drives the crushing knives 8 on the rotating shaft 9 and the tool holder fixing plate 10 to rotate rapidly through the belt drive module 3, thereby crushing the waste plastic. When there is metal in the waste plastic entering the crusher, the anti-loosening plate 11 can clamp and fix the crushing knives 8 to avoid the shaking of the crushing knives 8, and can also prevent the metal from entering the screw holes of the tool holder fixing plate 10, thereby avoiding the damage of the screw holes caused by the shaking of the crushing knives 8. When the tool needs to be repaired, the electric push rod 7 can push the crushing bin 5 to rotate upward, so that the crushing bin 5 turns upward and opens. The support arm 6 can support the opened crushing bin 5 to prevent the crushing bin 5 from tipping backward.

[0022] On one side of the lower end of the electric push rod 7, there is a motor 2. The output end of the motor 2 is equipped with a belt drive module 3. The belt drive module 3 includes a pulley and a triangular drive belt. The output end of the motor 2 drives the main pulley to rotate, thereby causing the main pulley to drive the driven pulley on the rotating shaft 9 to rotate through the triangular drive belt, making the crushing knives 8 on the rotating shaft 9 rotate rapidly, and then shearing and crushing the plastic.

[0023] The upper side of the crushing bin 5 is bolted to the feed bin 4. The support frame 1 and the bin 12 are bolted together. The motor 2 and the support frame 1 are bolted together.

[0024] The upper end of the electric push rod 7 is hinged to the crushing bin 5, and the lower end of the electric push rod 7 is hinged to the support frame 1.

[0025] The crushing knives 8 are bolted to the tool holder fixing plate 10, and the crushing bin 5 is hinged to the bin 12.

[0026] The anti-loosening plate 11 is welded to the tool holder fixing plate 10.

[0027] The working principle of the tool holder of the plastic crusher provided by the present invention is as follows: As Figures 1 - 5 shown in the figure, when plastic is being crushed, the plastic is fed through the feed bin 4, and the waste plastic enters the crushing bin 5. The motor 2 drives the crushing knives 8 on the rotating shaft 9 and the tool holder fixing plate 10 to rotate rapidly through the belt drive module 3, thereby crushing the waste plastic. When there is metal in the waste plastic entering the crusher, the anti-loosening plate 11 can clamp and fix the crushing knives 8 to avoid the shaking of the crushing knives 8, and can also prevent the metal from entering the screw holes of the tool holder fixing plate 10, thereby avoiding the damage of the screw holes caused by the shaking of the crushing knives 8.

[0028] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
